Abstract: 1,207,970. Making composite sheet; jointing by rolling; welding by pressure. JOHNSON, MATTHEY & CO. Ltd. 11 Dec., 1967 [20 Dec., 1966], No. 56889/66. Headings B3A, B3M and B3R. A copper or copper alloy substrate is coated or inlaid with a noble metal or alloy by locating an intermediate layer of nickel, iron, cobalt, molybdenum, or vanadium between the substrate and coating, and heating the assembly under pressure to bond the layers together. The noble metal may be gold, silver, platinum or palladium, and the layers may be bonded by hot pressing or rolling. Alternatively, the intermediate layer may be hot bonded to the noble metal or alloy, and the Cu or Cu alloy substrate then bonded to the bi-metallic product. The substrate can alternatively be electroplated with the intermediate layer, the bimetallic product then being bonded to the noble metal or alloy. In an example, Pd and Ni strips of 0À011 inch and 0À0275 inch thickness, respectively, were pressed together at 4000 p.s.i. and 900‹ C. in a non-oxidizing atmosphere. The Ni surface was then cleaned and pressed into contact with a 1 inch thick phosphor-bronze strip containing 4% tin at 3500 p.s.i. and 770‹ C. in a non- oxidizing atmosphere. The resulting composite strip was reduced to 0À0020 inch in four rolling steps with intermediate anneals.

Abstract: 1,174,910. Type-composing apparatus. LINOTYPE G.m.b.H. 21 Dec., 1966 [23 Dec., 1965], No. 57153/66. Heading B6W. Controlling from stored information.-A typebar-making or photographic type composing apparatus is controlled from stored information, e.g. perforated paper tape, by the steps of decoding the information, identifying each piece of machine function information and evaluating it in respect of its " time delay requirement " (the minimum time required for the machine to perform the function represented), entering the identified and evaluated information in a store, comparing it with at least one adjacent piece of identified and evaluated information to obtain the minimum or required time interval after which the information can become effective on the composing machine and releasing the information from the store at the termination of that minimum or required time interval. The apparatus according to the invention comprises a plurality of timing circuits where time constants single or in combination generate the delay required for each piece of information, and gate circuitry to release each piece of information from a store at the end of the time delay period allotted to that piece of information. Where two pieces of information in immediate succession are identical a larger delay than between two non-identical pieces of information is provided before the second piece of information becomes effective on the machine, also where two identical pieces of information are separated by a third, different piece of information, a shorter delay than between two non-identical pieces of information is provided before the second identical piece of information becomes effective on the machine. Spurious information, e.g. erase codings, which do not initiate machine functions are recognized and effect an acceleration of information scanning until machine function information is recognized. A delay to information representing an assembler-near matrix is initiated when this information is followed by that representing an assembler-far matrix.

Abstract: 1,209,716. Rotatable spinning ring. MAREMONT CORP. 3 Dec., 1968 [2 Jan., 1968], No. 57293/68. Heading DID. In a ring spinning frame having rotatable rings 30, each of which are mounted in a stationary housing 22 by a cushion of air, a brake means is carried by the stationary, spindle carrying rail 12 and engages the rings to cause retardation of their rotational movement when the rings carried by a ring rail 20 are moved to a lowered position with respect to the normal traversing range at the conclusion of the bobbin winding. The brake means preferably comprises a friction pad 54 which is resiliently mounted on the spindle rail 12 between each pair of spindles 13. In the lowered position flanges 33 of the rings which extend beneath the ring rail 20 contact the pad. Consequential upward displacement of ring 30 is minimized by providing a retainer member 38 held in place by clips 28 and projections 23 on housing 22. Normally compressed air supplied to housing 22 through pipe 21 passes through apertures 27 in the housing to provide a cushion of air between the housing and the ring, the air escaping in direction P between the lower surface of a flange 36 on the ring and the upper surface of the housing. Centrifugal force also causes air to flow in direction C between the top surface of the flange 36 and the under surface of the retainer member 38, which member is of reduced thickness at its inner periphery which is spaced from the ring.

Filed: 1972-12-12
Abstract: 1390218 Character recognition systems DATA SOURCE CORP 12 Dec 1972 [28 Feb 1972] 57315/72 Heading G4R A clockless system for recognizing numerals formed of horizontal and vertical stroke elements comprises an array of detectors which is swept over the characters. The detector outputs resulting from the scanning of the same stroke element are staggered, one to another, by feeding some of them to delays or by physical separation of the detectors in the direction of scan. The numerals may be printed or embossed on a document and sensed by 5 photo-cells. Each numeral is formed of up to 3 horizontal strokes c, d, e, and up to 4 vertical strokes a, b, f, g, all 7 being used to form numeral 8, Fig. 2. The photo-cells R-U may be staggered as shown. Consequently, when the array is moved horizontally across the numeral T and U will give an output in response to strokes a and b prior to output from Q, R, and S. The photo-cells feed logic circuitry, Fig. 6 or 8 (not shown), which takes account of the order of occurrence of the outputs to develop a 7-bit output indicative of the presence and absence of respective ones of the 7 possible strokes defining the numeral. Because it is the order of occurrence and not the actual time of occurrence or duration of the signals that is significant the system is independent of the rate of scan, so the document may be moved manually across the array. The logic circuitry is insensitive to variation in the width of vertical strokes and to the length of the space between numerals, and is inhibited if the numerals scanned are insufficiently tall.

Abstract: 1285775 Aritiskid braking systems ROBERT BOSCH GmbH 26 Nov 1969 [27 Nov 1968 (2)] 57847/69 Heading F2F [Also in Division G1] In a wheel slip sensing arrangement in which is obtained a pulse train the pulse frequency of which is dependent upon the angular velocity of the wheel, a monostable multivibrator 31, Fig. 2, having its ON period varied in accordance with the average value of the angular velocity, has its output applied to one input of a NOR circuit 29 to the other input of which is applied a signal indicative of the pulse train whereby a signal is produced by the NOR circuit when the period between the pulses of the pulse train exceeds a predetermined level. Positive pulses from pulse generator 18 coupled to the vehicle axle 13 are applied to the input of monostable circuit 28, one output of which is applied directly to NOR gate 29 and the other output of which is applied to trigger monostable 31 the relaxation period of which is controlled in accordance with the average value of the output from monostable 28 obtained from integrator 32. During admissible variations in the rotational speed of wheel 11 during breaking the relaxation time of monostable 31 is immediately followed by a pulse from the monostable 28 so that NOR gate 29 is not activated. If the wheel begins to lock the pulses from monostable 31 are such as not to fill the intervals between the pulses of monostable 28, Fig. 5 (not shown), so that NOR gate 29 is activated and the output pulse is applied to brake cylinder 15 to reduce the breaking force. In an alternative embodiment, Fig. 6 (not shown), the output from the pulse generator is applied to a bi-stable multivibrator the outputs of which are fed directly to the input of a NOR gate and via a monostable circuit and integrator to a second monostable whose output is applied to the other input of the NOR gate. The pulse generator 18 may be of the variable reluctance type, electromagnetic or light.
